SHOCK-COMPRESSOR.

Specification of Letters Patent.

Patented Apr. 24, 1917.

Application filed March 27, 1916. Serial No. 87,036.

a simple and convenient means for compressing shocks of corn and the like before tying the same with a cord.

Another object of this invention is to provide a device of this character which is simple and durable in construction, inexpensive to manufacture, and one which will be very efiieient in operation.

With these and numerous other objects in view, my invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to and more particularly pointed out in the specification and claim.

In the accompanying drawings:

Figure 1 represents a plan view of my im proved shock compressor showing the rope or cord in the position which it will assume when around a shock;

Fig. 2 is a side elevation of the invention;

Fig. 3 is a central vertical longitudinal section taken on the line 33 of Fig. 1;

Figs. 4, 5, and 6 are vertical transverse sections taken respectively on the lines 4-4, 55 and 66 of Fig. 1, and

Fig. 7 is a detail perspective view of one of the supporting arms 22.

In the accompanying drawings, the numeral 1 designates a substantially rectangular frame, which is provided with upright sides 2, a rounded rear end 3, and a front end 4 which has a notched upper edge 5. Centrally disposed in the notched portion of the front end 4 of the frame 1 is a forwardly projecting integral thrust pin 6, and positioned adjacent either side of the same, within the notch 5 and in a horizontal plane slightly above the horizontal plane of the pin 6, is a pair of vertically disposed com pressing cord guiding puleys 7 and 8, which are mounted in openings through the front 4 adjacent either side of the notch 5. A

portion of the bottom of said notch is inclined downwardly toward the pulley 7 The pulleys 7 and 8 have their upper ends mounted in a bearing 9 in the upper edge of the forward end 4 of the frame, and have their lower ends mounted in a bearing 10 in the lower edge of the front end of the frame. The bearing 9 for the pulley 8 is provided at its outer end with a guard 11 which is formed at one side of the opening and which projects downwardly therefrom and is connected with the upper portion of the notched portion 5 of said front end of the frame adjacent the thrust pin 6. Projecting through the front end of the frame adjacent the last mentioned pulley is an opening 12 which is adapted to receive the binding cord therethrough, in a manner to be hereinafter more fully described.

Disposed within the sides 2 0f the frame 1, and adjacent the rear end 3 of the same, are bearings 18 in which is mounted a transversely extending compressing cord holding drum 14 which is rotatably mounted therein and operated by a handle 15 secured to one end 16 of the same, which projects through one of the sides 2. Secured to the projecting end 16 of the drum 14 and outside the frame 1, is a ratchet wheel E. A pawl H, consisting of a lever I, pivoted at its middle on the outside of the side 2 of the frame 1 has an outwardly bent handle J at one end, while the inner end is adapted to normally engage the ratchet wheel E, but may be moved out of engagement therewith when the handle is depressed. By this means it will be obvious that the drum 14 may be easily rotated in one direction, but will be prevented from moving in the other direction unless the handle J of the lever I is operated. Secured at one end to the outer surface of the drum 14 is a compressing cord 17 which projects forwardly along the frame 1, and over the vertical pulley 8 in the front end of the same. This cord is adapted to be positioned around the shock, and back over the pulley 7 in the-front end of the frame, and has its opposite end removably secured to the drum 14. When in this position, it will be obvious that upon rotation of the drum 14, the cord 17 will compress a shock held therebetween, to the desired tightness, whereby the binding cord may be easily tied therearound. The shock will be held securely by the thrust pin 6. The inclined bottom face of the notch 5 will guide,

the cord against the pulley 7 when the cord is being placed in position.

The spool of binding cord 20 which is used in connection with this device, is supported in a sheet metal receptacle 21 which is suspended beneath the rectangular shaped frame 1 by means of a pair of substantially L-shaped rearwardly bent arms 22. These arms 22 have their horizontally disposed portions 23 secured on opposite sides of the receptacle 20, and the extremities of the vertical portions 24 of the same are reduced and bent laterally to form lugs which are adapted to be sprung through openings 25 disposed in the sides 2 of the frame 1 adjacent the transversely extending drum 14:. These laterally bent lugs 24 of the arms 21 are positioned. between the sides 2, and project outwardly therefrom through the openings 25. Positioned on the-arms 21 a short distance below the bent ends of the same, are laterally projecting fiat transversely extending shoulders 26 which are adapted to receive the lower edges of the sides 2 of the frame. By this means, the binding cord holding receptacle will be securely suspended beneath the frame 1 parallel therewith,

and will be removably connected to the same. This removable connection is brought about by the fact that the upper ends of the arms 21 are detachably connected with the frame, by being sprunginto engagement with the opposite sides thereof, whereupon the arms may be easily disconnected from the sides of the frame, to which they are connected.

When the device is used, the pin 6- is inserted in the shock, and the compressing cord is passed around the shock and secured to the drum, whereupon the shock may be drawn tightly together by winding the cord upon the drum. The cord may be held drawn by means of the bolt engaging the ratchet wheel, at the side of the frame, and the shock may be bound by the binding cord, which comes out from the spool held within the receptacle, and extends through the opening 12 in the front end of the frame,

where it may be wound around the compressed shock, tied, and severed from the spool, by means of a knife 30 which is secured to the upper edge of the frame, as clearly shown in Figs. 1 and 2 of the draW ings.

From= the foregoing description, the construction and operation of this shock compressing device will-be readilyunderstood and it will be seen that I have provided a simple and eflicient means for carrying out the objectseof this invention. Attention is especially lirected to the extreme simplicity of the contruction of this device, and the fact that the rectangular shaped frame and thrust pin are formed integrally. Thistlevice forms a very small and compact, yet efficient shock compressor which'will operate in a convenient and thorough manner.

I claim:

A shock compressor comprising a substantially rectangular-shaped frame, an integral thrust pin projecting from the front of said frame, said front of the frame having a notch in its upper edge with an inclined bottom face, the front of the frame having spaced openings therethrough spaced on opposite sides of the notch, one of said openings communicating with the notch and disposed adjacent the lower edge of the inclined face in its bottom, vertically disposed pulleys mounted in said openings, a transversely disposed rotatable drum mounted in said frame, and a compressing cord surrounding the shock with its opposite ends secured to said drum and adapted to operatively engage the pulleys through the front ofthe frame.

In testimonywhereofl have .hereunto set my hand in presence of two subscribing witnesses.
